Solidata K5-32 solid-state drive
Solidata's SLC-based solid-state drive is energy efficient, but it has poor write performance
- Comparatively low cost per gigabyte, good read performance, low power consumption
- Poor write performance with large files, low IOPS for an SLC drive
Solidata's K5-32 solid-state drive uses single-level cell (SLC) memory, which should suit IOPS-intensive applications in servers and RAID arrays. Unfortunately, real-world write performance is poor compared to other solid-state drives and some conventional hard drives.
Price$ 359.00 (AUD)
The Solidata K5-32 is a 2.5in, 32GB solid-state drive (SSD). It features single-level cell (SLC) memory, which allows it to provide higher input/output operations per second (IOPS) than drives with multi-level cells (MLC). This makes it a good choice for servers, workstations and high-end desktops, but it does come with a high-end price tag to match.
It has a formatted capacity of 29.8GB and a cost per formatted gigabyte of $11.21. This price is almost twice as expensive as the MLC-based Solidata K6-32 SSD. Thankfully, as far as SLC solid-state drives go, the K5-32 is still a relatively good buy; the Kingston 80GB SSDNow M Series solid-state drive has an even higher price of $16.72 per formatted gigabyte.
Of course, there is a reason you’re shelling out the extra cash: SLC memory generally offers higher IOPS than MLC memory, which means that it can handle more operations in a shorter amount of time. This makes it a viable option for servers and storage area networks (SAN). Solidata quotes the K5-32 SSD at 7000 IOPS for write operations and 7500 IOPS for read operations; by contrast, the Kingston SSDNow E series manages 35,000 IOPS for write operations and 3300 IOPS for read operations. Though SLC solid-state drives offer higher input/output operations in a given period, they don't necessarily offer better performance in tasks that don't require sustained throughput. In our tests, we transferred both large and small files between the K5-32 SSD and a 300GB Western Digital VelociRaptor test drive. In our large file test — transferring 20GB of 3-4GB files — the K5-32 SSD had a write speed of 42.4 megabytes per second, a read speed of 76.9MBps and it performed a simultaneous read/write operation at a rate of 37.1MBps. These transfer speeds are faster than the MLC K6-32 SSD, but still slow when compared to other solid-state drives like the MLC-based Intel X25-M.
Our small file test consisted of transferring 3GB of 1MB files. The K5-32 solid-state drive wrote this data at a rate of 34.1MBps, read it at 50.6MBps and performed a simultaneous read/write operation at a rate of 26.8MBps. Overall, these transfer speeds are on par with the K6-32 SSD.
Thankfully, solid-state drives aren't purely about performance; they are also cooler, quieter and more power efficient than conventional hard drives. The K5-32 SSD is particularly frugal when it comes to power consumption. During our tests, it consumed 0.4 Watts when idle, and a maximum of 1.06W when writing data. Overall power consumption is slightly less than the MLC-based K6-32 SSD and significantly less than Intel's X25-M solid-state drive, which had erratic power usage during our tests. These power savings certainly add up when multiple solid-state drives are used in a RAID array or employed in a 24/7 role.
The Solidata K5-32 solid-state drive has a 2.5in form factor and is 9.5mm thick. This makes it suitable for use in all SATA-based notebooks that have a 2.5in drive bay. However, the K5-32's is better suited to servers, SANs or 2.5in network-attached storage devices like the QNAP SS-439 Pro Turbo NAS.
The Solidata K5-32 solid-state drive is an affordable option for IOPS-intensive enterprise applications such as virtual machines and high-capacity storage arrays. It has low power consumption and operates silently. At 32GB, however, it won't replace conventional hard drives, and it’s much slower than other SLC-based and even MLC-based solid-state drives.

The HP OfficeJet 250 Mobile Printer is a great device that fits perfectly into my fast paced and mobile lifestyle. My first impression of the printer itself was how incredibly compact and sleek the device was.
Wireless printing from my iPhone was also a handy feature, the whole experience was quick and seamless with no setup requirements - accessed through the default iOS printing menu options.
A smarter way to print for busy small business owners, combining speedy printing with scanning and copying, making it easier to produce high quality documents and images at a touch of a button.
I've had a multifunction printer in the office going on 10 years now. It was a neat bit of kit back in the day -- print, copy, scan, fax -- when printing over WiFi felt a bit like magic. It’s seen better days though and an upgrade’s well overdue. This HP OfficeJet Pro 8730 looks like it ticks all the same boxes: print, copy, scan, and fax. (Really? Does anyone fax anything any more? I guess it's good to know the facility’s there, just in case.) Printing over WiFi is more-or- less standard these days.
As a freelance writer who is always on the go, I like my technology to be both efficient and effective so I can do my job well. The HP OfficeJet Pro 8730 Inkjet Printer ticks all the boxes in terms of form factor, performance and user interface.
I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.
